DIY Subwoofer- other recommendations?

[Eric Z]

I building a new HT in my family room and heard about DIY kits for a subwoofer. I've heard a few people mention Parts Express and various Titanic MKIII subwoofer kits. Here's the 10" specs-

I am wondering if anyone has experience with the quality of this sub. I've never done anything DIY with audio equipment so I'm a little hesitant- especially because I can't audition it before I buy it.

I would like to spend as little as possible for this sub ($350 max) since this is for an additional HT, but of course get as good of quality as possible.

I currently use a Def Tech PS80 in my main HT and I'm happy with that- some say it's too small, not deep/tight enough, but it sounds good enough for me!

Any information is appreciated!

As always, thank you!

P.S. The room this is going in is a carpeted lower level family room- about 12x18. It only has one door opening in the rear of the room.

I'd give this a serious look. Great sub, already built, costs less...

You may want to consider building from scratch as well. There are plenty of freeware programs available (winisd) that can show you all you need to know about box spec/tuning. All you need is a reputable sub within your budget and the T/S parameters (though many are included in the softare). Basic woodworking skills will bring pretty good results.

I went this route last year and built a ported isobaric sub that's -3bd@22.5hz using drivers and scrap materials I had laying around. Great for HT use.

Adire Audio includes plans for DIY subwoofer enclosures that work for their drivers. I made one of the enclosures for the Tempest with two 15" passive radiators and it is an amazing sounding setup.
